WebIn fluid dynamics, drag(sometimes called fluid resistance) is a forceacting opposite to the relative motion of any object moving with respect to a surrounding fluid.[1] This can exist between two fluid layers (or surfaces) or between an fluid and a solidsurface. WebFeb 20, 2011 · That volume is a cylinder with area A2 and length/height L. L is equal to the distance that the water have traveled during t and since its velocity is v2, L = t · v2. Therefore the …

WebJul 20, 2024 · When a solid object moves through a fluid it will experience a resistive force, called the drag force, opposing its motion. The fluid may be a liquid or a gas. This force is a very complicated force that depends … WebFigure 1: Fluid flow between two coaxial cylinders In (1), U is the velocity along the cylinder (i.e., the z component of velocity), µ is the viscosity, L is the length of the region along the cylinders in which the flow is fully developed, P 1 and P 2 are the pressures at z = 0 and z = L, respectively. P 1 and P 2 represent the

WebSo, if a certain amount of fluid (volume) passes through area 1 in a certain amount of time (flux - R) the same volume will cross section 2.
